They (on the PFI board) are also wondering if this could be the same guy who was tested for Ebola a week ago in Dublin and came back negative. Imagine the ramifications on that one, if it is, and he actually WAS...
Given all the people who have been tested for ebola with good suspicions, it stands to reason there has been at least one statistical false negative.
Just how many is another question.
